With Île-de-France as its stratotype region, the Lutetian is an internationally recognized and even famous geological stage. The fossils found in it, the monuments built with stone of that age and the historical figures who took an interest in it all justify this notoriety.

International stage stratotypes
1996All of the Upper Carboniferous stages in the so-called ‘Heerlen Classification’, from the Chokierian to the Bolsovian, have their base stratotypes in northern England (the Westphalian D base stratotype has yet to be selected, although sites in South Wales will probably be strong contenders).

Stratotype of Ordovician Whiterock Series
PALAIOS, 1991Here the authors reaffirm and document fossil ranges at the stratotype section for the base of the Whiterock Series in Whiterock Canyon, northern Monitor Range, Nevada, and designate a reference section at Meiklejohn Peak, Bare Mountain quadrangle, Nevada.

Iridium Abundances Across the Ordovician-Silurian Stratotype
Science, 1986Chemostratigraphic analyses in the Ordovician-Silurian boundary stratotype section, bracketing a major extinction event in the graptolitic shale section at Dob's Linn, Scotland, show persistently high iridium concentrations of 0.050 to 0.250 parts per billion. There is no iridium concentration spike in the boundary interval or elsewhere in

Introduction to Part A Chronostratigraphic units: Historical stratotypes and global stratotypes
1995Publisher Summary This chapter discusses historical and global stratotypes. In agreement with common usage, the word “stage” is used in this presentation; both for the actual rocks deposited during an interval of time, and for the interval of time itself (sometimes called “age”).

Abstract Stratigraphy is a magnificent subject—magnificent in its breadth and scope, magnificent in its importance to so many lines of human endeavor. It is essentially that branch of geology which deals with the arrangement, the distribution, and the chronological succession of rock strata (and other associated rock bodies), with respect to any or

Unit stratotypes for global stages: The Neogene perspective
Earth-Science Reviews, 2005Abstract Recent developments in integrated high-resolution stratigraphy and astronomical tuning of continuous deep marine successions invalidate arguments against the designation of unit stratotypes for global stages, the basic building blocks of the standard Global Chronostratigraphic Scale (GCS).
